Furthermore, whilst the overexpression of a wild type form of tai alone in clones did not induce tumour formation (Figure 3D) and adult flies eclosed (data not shown), overexpression of tai in scrib mutant clones was sufficient to induce clonal overgrowth and tumour formation throughout an extended larval stage, in a similar manner, albeit with less potency, as ab overexpression (Figure 3E–G). Here, SCRIB is linked to neoplasm.
